Stock Market Crash of 1929: This was a major stock market crash that occurred in late October 1929. It started on "Black Thursday" and ended on "Black Tuesday". It's like different stages of that thunderstorm causing havoc at our concert.
Great Depression: A severe worldwide economic depression that took place mostly during the 1930s, beginning in the United States. The effects were felt for over a decade, much like how it takes time to recover from damages caused by a severe storm.
New Deal: A series of programs, public work projects, financial reforms, and regulations enacted by President Franklin D. Roosevelt in response to the Great Depression. Imagine this as rebuilding efforts after our hypothetical storm has passed.
